Question

worksheet: the four fundamental forces of nature | definition & overview https://study.com/learn/lesson/four - fundamental - forces - of - nature.html 1. which of the following objects can produce a gravitational force on another object? a moon a car all of the answers are correct a sheet of paper 2. using what you know about electromagnetic force, what happens when an electron approaches another electron? they attract each other. the charges on the neutrons change from negative to positive. nothing they repel each other. 3. which of the four fundamental forces of nature has the shortest range? electromagnetic force strong force gravitational force weak force 4. which of the following is false about the electromagnetic force? electrons in one object repel electrons in another object. it is the strongest of the four fundamental forces. it means that atoms never really touch. it extends to all contact forces, such as kicking a ball. 5. which of the following is caused directly by the strong force? electricity flowing through a wire the tides on the earth beta decay the existence of atomic nuclei

Explanation:

1. Any object with mass can produce a gravitational force. A moon, a car, and a sheet of paper all have mass, so they can exert gravitational force on other objects.
2. Electrons have a negative charge. Like - charged particles repel each other according to the electromagnetic force.
3. The weak force has the shortest range among the four fundamental forces. It acts over a distance of about \(10^{-18}\) meters.
4. The strong force is the strongest of the four fundamental forces, not the electromagnetic force.
5. The strong force holds protons and neutrons together in the atomic nucleus, thus enabling the existence of atomic nuclei.

Answer:

1. All of the answers are correct.
2. They repel each other.
3. Weak force
4. It is the strongest of the four fundamental forces.
5. The existence of atomic nuclei
